Brake pedal locking apparatus

Abstract

A brake pedal locking apparatus, the apparatus comprising a latching groove formed at a surface of a brake pedal; a hook device having a hook head for inserting into the latching groove to fix a brake pedal in its pushed position; a housing having a hook device receiving cavity therein and a penetrated hole for a hook device to protrude therethrough; a compression spring for pushing the hook device to protrude out of the penetrated hole; and an operational lever connected to the hook device by a wire for pulling the hook device into the housing.

What is claimed is: 
     
       1. The combination of a brake pedal and an apparatus for locking a brake pedal into a pushed position comprising: a latching groove formed at a surface of the brake pedal;   a hook device having a hook head for inserting into the latching groove to fix the brake pedal in the pushed position;   a housing having a cavity for receiving the hook device therein, and a penetrated hole for the hook device to protrude therethrough;   a first compression spring for pushing the hook device to protrude out of the penetrated hole for inserting into the latching groove when the brake pedal is in the pushed position; and   an operational lever connected to the hook device by a wire for pulling the hook device into the housing and releasing the brake pedal from the pushed position.   
     
     
       2. The apparatus as claimed in claim 1 wherein said latching groove is funnel-shaped so that the hook head is prevented from being detached from the latching groove when the hook device is inserted into the latching groove. 
     
     
       3. The apparatus as claimed in claim 1 or claim 2 wherein said hook head includes two hook members connected rotatively on a hinge pin and a second compression spring installed between the hook members to provide the hook members with a spreading force. 
     
     
       4. The apparatus as claimed in claim 1 wherein said hook head is inserted into a hole formed on the front end of the hook device and mounted to the hook device by a pin. 
     
     
       5. The apparatus as claimed in claim 1 wherein said hook device includes two latching projections formed protrudingly and resiliently opposing each other at one end by the first compression spring placed in the latching projections. 
     
     
       6. The combination of a brake and an apparatus for locking a brake pedal into a pushed position comprising: a latching groove formed on a surface of the brake pedal;   a movable latching member for fixing the brake pedal in the pushed position separatively inserted into the latching groove when the brake pedal is in the pushed position;   a shifting means for shifting the latching member to be inserted into the latching groove;   a return means for separating the latching member inserted into the latching groove from the latching groove; and   a guide means for guiding the latching member.   
     
     
       7. The apparatus as claimed as claim 6 wherein said shifting means comprises two adjuster projections located protrudingly on a surface of the latching member with a predetermined space therebetween, a rotational lever one end of which is located between the adjuster projections and the other end of which is connected with a rotational shaft, an operational lever, and a wire for connecting the operational lever and the rotational lever so that moving the operational lever rotates the rotational lever. 
     
     
       8. The apparatus as claimed in claim 6 wherein said guide means comprises a housing of a vacant box shape having a latching member guide hole on the front surface and a wire guide hole on the rear surface. 
     
     
       9. The apparatus as claimed in claim 7 wherein a pin is formed integral with the lower surface of the housing and the rotational lever is coupled to the pin rotatively. 
     
     
       10. The apparatus as claimed in claim 7 wherein said return means comprises a return spring one end of which is coupled to the rotational shaft of the rotational lever and the other end of which is coupled to a projection formed protrudingly on the lower surface of the housing.
